中文摘要:

      基于1995—2018年省级层面相对价格水平数据,从区域价格收敛这一视角出发,采用空间计量模型测度并分析中国国内市场一体化的演变特征。研究发现:1995年以来,中国国内市场一体化速度总体不断提升,同时呈现出“下降—上升—小幅回落—企稳回升”的阶段性变化特征,并且这一结果在采用非参数时变系数面板模型后依然成立；国内市场一体化水平的演变存在明显的地区间差异,西部地区的市场一体化进程明显慢于东部和中部地区。研究认为,中国国内市场一体化的阶段性演变特征主要可归因于改革红利的“螺旋效应”,而地区间产业同构竞争、对外开放程度等也是重要的影响因素。随着供给侧结构性改革的深入推进,中国国内市场一体化即将进入新一轮发展机遇期。

英文摘要:

      Based on the provincial relative price level data during the years from 1995 to 2018, from the perspective of regional price convergence, this paper adopts the spatial econometric model to measure and analyze the characteristics of evolution in China's domestic market integration. The research finds the following. First, China's domestic market integration level has been generally improving since 1995. At the same time, it presents the characteristics of periodic changes of “decline, rise, slight decline, stabilization and recovery”. Moreover, this result is still valid under the nonparametric time-varying coefficient panel model. Second, there is obvious regional difference in the evolution of domestic market integration, with market integration in western region significantly slower than in eastern and central parts. The research finds that the characteristics of periodic evolution in China's domestic market integration can be mainly attributed to the “spiral effect” of reform bonus. The isomorphism competition in regional industry, the degree of opening up to the world, etc. are also important factors. 
